I check on the singer site and cannot find the price for my singer G-8018456 made in November 2 1910 in elizabeth nj only 3000 were made... can anybody help me??

I hope someone is able to give you an answer you might prefer to hear:

This G - series, this one sold for $15:

One similar to the above was listed on eBay for $220. It received no bids.

One has been listed and re-listed on eBay for $125 with no takers that was also made in 1912:

So folks have sold them for $15 and are trying to get $125 but are not, at least to my knowledge. I have one I was not able to sell or give away and now use a hallway table and it is lovely for that purpose.
